> You usually define server-side configs (`import { config } from 'telefunc'`) at your server entry. For example if you use [Express.js](https://expressjs.com/):
> ```ts
> // /server/index.ts
> // Environment: server
>
> import express from 'express'
> import { config } from 'telefunc'
>
> const app = express()
>
> // Config values can be set here
> config.someServerSideSetting = 'some-value'
> ```
